Key takeaways
- The most common new traffic controller mistakes are poor positioning, no escape route, turning away from traffic, unclear bat signals and loose radio calls.
- Most mistakes come from nerves and lack of practice, not carelessness, and are fixed by coaching on the spot.
- Pair new controllers with an experienced buddy and give them simpler positions first.
- Coach with one point at a time, show rather than tell, and check the fix later in the shift.
- Record coaching so the next supervisor knows what the new starter is working on.
The new traffic controller mistakes supervisors see most are standing in the wrong place, having no escape route, turning away from traffic, giving unclear bat signals and making loose radio calls. Nearly all come from nerves and lack of practice. They are fixed by a buddy, simpler first positions and calm, specific coaching on the spot.
Every experienced controller made some of these mistakes in their first weeks. The difference between a new starter who becomes a good controller and one who leaves, or gets hurt, is usually the quality of coaching on those first shifts. This guide is for supervisors and team leaders, and for new controllers who want to know what to watch for.
The ten mistakes supervisors see most
| # | Mistake | Why it matters | Quick coaching fix |
|---|---|---|---|
| 1 | Standing in the traffic lane or too close to it | No room if a driver does not stop | Show the position the plan intends and mark it |
| 2 | No escape route | Nowhere to go if a vehicle comes through | Walk the escape route together before the first cycle |
| 3 | Back to traffic | Cannot see what is coming | Face approaching traffic, turn the body not the head |
| 4 | Bat held low, half turned or switched mid-approach | Drivers misread the signal | Hold the bat up, square to the driver, change only when traffic has stopped |
| 5 | Releasing without confirming the other end | Head-on conflict in the open lane | Never release until the other end confirms it is holding |
| 6 | Loose radio calls | Missed or misheard instructions | Use call signs and confirm every call |
| 7 | Phone out while on position | Lost attention | Phone away; radio only |
| 8 | Arguing with drivers | Escalation, distraction | Short scripted answer, then back to the job |
| 9 | Not watching the work crew | Plant moving into the open lane | Glance at the work area every cycle |
| 10 | Not reporting problems | Small issues become big ones | Praise every report, however small |
Several of these come back to bat technique. Our guide to stop/slow bat technique explains positioning and signals in detail.
Why new controllers make these mistakes
Understanding the cause helps you coach the fix.
- Nerves. Standing a metre or two from moving traffic is unnatural. Nervous people freeze, over-signal or look away.
- Training versus reality. A practical assessment on a quiet site is different from a busy road with a bus behind a truck.
- Wanting to please. New starters let impatient drivers through early, or let the work crew move plant without calling it.
- Information overload. A first briefing can be a lot to take in. Things like call signs and escape routes get lost.
- Fatigue. Early starts, heat and long shifts hit new starters hardest because they have not yet learned how to pace themselves.
A first-shift coaching example
Example scenario: a new controller (TC 2) is on their second shift, working stop/slow at the northern end of a single-lane closure on a suburban road. The team leader has placed an experienced controller (TC 1) at the southern end and is supervising from the work area.
Before the first cycle. The team leader walks TC 2 to the position, shows where to stand so approaching drivers can see the bat clearly, and points out the escape route behind the parked cars onto the footpath. They do a radio check together. The team leader says: "You only release when TC 1 says they are holding. If in doubt, hold."
First fifteen minutes. The team leader watches from a safe spot. TC 2 holds the bat at chest height and keeps glancing at the work area with their back half-turned to oncoming traffic.
Coaching point one. At a natural break, the team leader walks over and says privately: "You're doing well holding traffic. One thing: keep your body facing the cars coming at you. Turn your whole body to look at the work, then back. Watch me." They demonstrate, then watch two more cycles. TC 2 gets it.
Mid-morning. A driver yells and edges forward. TC 2 steps toward the car to argue. The team leader radios: "TC 2, step back, hold, I'm coming." Afterwards, privately: "Never move toward a vehicle. Step back to your escape route if you need to. What you say to drivers is short: 'Won't be long, thanks for waiting.' Then back to your job." Our article on abuse of traffic controllers covers how companies support controllers through this.
After lunch. The team leader checks both fixes: body position is good, and when another driver complains TC 2 uses the short script and stays put. The team leader tells them so.
End of shift. The team leader records two coaching points and one thing done well, so the next team leader knows what TC 2 is working on.
How good supervisors coach
| Do | Don't |
|---|---|
| One point at a time | Give a list of ten corrections |
| Show, then watch them do it | Just describe it |
| Correct privately | Correct over the radio or in front of the client |
| Use plain words | Use jargon the starter has not learned yet |
| Check the fix later | Assume it stuck |
| Praise reporting and good calls | Only speak up when something is wrong |
| Record what they are working on | Rely on memory |
Except when it is urgent. If a controller is about to be hurt, stop them immediately over the radio or in person. Coaching can wait; safety cannot.
Setting new starters up to succeed
Many mistakes can be prevented by how the first shifts are rostered:
- Pair them with an experienced buddy for the first shifts.
- Start with simpler positions, such as a pedestrian detour or a quiet end, before high-volume stop/slow.
- Avoid night and high-speed work until they have a few good day shifts.
- Keep shifts reasonable. Fatigue makes everything harder; respect your company's fatigue limits.
- Make the briefing easy to follow with the same order every time.
- Make it safe to ask questions. A new starter who asks "where do I go if a car comes through?" is doing the right thing.
New controllers can prepare too. Our guide to your first week as a traffic controller sets out what to expect and what to bring.
Mistakes during set-up and pack-down
New controllers are most exposed when they are carrying signs and cones, not when they are standing on position. Their attention is on the equipment and they often walk with their back to traffic. The common slips:
- Walking in the live lane to save a few steps, instead of on the shoulder or footpath side.
- Placing signs out of order, for example putting the taper out before the advance warning signs, so drivers meet cones with no warning.
- Leaving a sign face-down or turned the wrong way when a gust catches it, and not going back.
- Forgetting to cover a permanent sign that conflicts with the temporary ones, such as a speed sign.
- Collecting the advance signs first at pack-down, leaving the taper and work area with no warning behind them.
- Getting out of the ute on the traffic side.
Coaching fix: on the first few set-ups, have the new starter walk with the team leader or buddy, carry fewer items at a time and say out loud which sign comes next. Explain the reason for the order, not just the order: advance signs first so drivers are warned before they reach anyone on the road, and the reverse at the end so the warning is the last thing to go. Once they understand why, the order sticks.
Radio slips and how to fix them
Radio mistakes are common because new starters are self-conscious on an open channel. Common slips and fixes:
- No call sign: "Ready" means nothing if you do not say who you are. Practise "TC 2 to TC 1, holding north."
- Talking over others: wait for a pause and press the button before speaking.
- No confirmation: every instruction gets a reply, even just "TC 2, copy."
- Describing the wrong car: describe the last car clearly, such as colour and type, so the other end knows when the lane is clear.
- Assuming silence means yes: if the other end does not answer, keep holding and call again. No reply is never a confirmation.
A quick fix for radio nerves: before the first cycle, have the new starter and their buddy run three practice exchanges off the open channel, or at a quiet moment, using the exact words they will use on the day. Hearing themselves say "TC 2, holding south, copy" once or twice takes most of the awkwardness away.
A coaching record template
Keep a short record for each new starter for their first weeks:
- ☐ Date, site and position worked.
- ☐ Supervisor or buddy.
- ☐ What went well.
- ☐ Coaching points given (one or two).
- ☐ Whether the fix was checked later in the shift.
- ☐ Any incident, near miss or abuse.
- ☐ Next focus.
- ☐ Ready for: busier stop/slow, night work, higher-speed roads (yes or not yet).
Records help the next supervisor and show the company is training people properly. Our guide to traffic controller safety risks covers the hazards your coaching is trying to control.

Next steps
Pick one coaching habit from this guide and use it on your next shift with a new starter. If you roster crews, TrafWise checks clashes and fatigue limits on the allocation board and tracks crew ticket expiry, which makes it easier to pair new starters with experienced buddies.
Frequently asked questions
What is the most dangerous mistake a new traffic controller makes?
Standing in the wrong place without an escape route, especially in the path of traffic or with their back to it. If a driver does not stop, the controller needs somewhere to go. Supervisors check each position and escape route in the briefing and again once controllers are in place.
How do supervisors coach new traffic controllers?
Good supervisors pair new starters with an experienced controller, give them simpler positions first, watch them for the first cycles, correct one thing at a time, demonstrate the right way and check the fix later in the shift. They keep feedback private and specific, and record what the new starter is working on.
Is it normal to feel nervous on your first traffic control shifts?
Yes. Most new controllers feel exposed standing near traffic and dealing with impatient drivers. Nerves usually fade with practice, a supportive buddy and a clear routine. Tell your supervisor if you feel unsafe; a good one will adjust your position and talk you through it.
What should a new traffic controller do if a driver ignores the stop bat?
Do not step in front of the vehicle. Move to your escape route, radio the other end and the team leader immediately, note the vehicle details if safe, and let the team leader decide what to report. Your safety comes before stopping any vehicle.
How can new traffic controllers handle abusive drivers?
Stay calm, keep your distance, do not argue and do not engage. Keep controlling traffic, radio your team leader, and step away to safety if the driver becomes threatening. Report the incident at the end of the shift or sooner if needed. Companies should have a procedure and support for controllers who are abused.
